Fuel Pump Replacement

What is a fuel pump?

The fuel pump's main responsibility is to deliver gas from the fuel tank to the fuel injectors. The pump must deliver the right amount of fuel and at a high enough pressure to keep the engine running smoothly in all conditions.

How does the fuel pump work?

Fuel pumps on most cars and trucks use an electric motor to drive a fluid pump. The pump can be either inside or outside the fuel tank. Either way, the fuel is sucked out of the fuel tank and pushed through a line to a filter, and then to the fuel injectors.

What are the symptoms related to a bad fuel pump?

If the fuel pump leaks or begins making a lot of noise, get it looked at right away. A failing fuel pump will not create enough pressure in the fuel system, possibly causing a loss of engine power or preventing the car from starting. It may also cause the check engine light to come on.

Can I drive with a fuel pump problem?

Driving with a failing fuel pump is a bad idea. In some cases, the car won't even start or run, preventing you from driving at all. 

If the car is running but has a lack of power or keeps stalling because of a suspected fuel pump problem, we recommend driving it to a safe spot and then having it towed to a shop for repairs.

How often do fuel pumps need to be replaced?

Fuel pumps do not have a specific replacement interval. Replacement becomes more common as the mileage on the car increases. Repeatedly running the fuel tank low or driving with clogged fuel filters can put additional strain on the fuel pump, shortening its lifespan.
